I tried to copy this soup from Campagne.  It ended up being a combination of 2 different recipes.  Here goes:

1 lb carrots, chopped and peeled; 1/2 onion, sauteed with garlic

1/4th teaspoon cumin, herbs de provence, salt and pepper

Simmer for 20-30 minutes.  Puree in blender.

Mix in a small amount of whipping cream.
